Abstract

Genetic screening is the systematic search in a population for individuals with a particular genetic disease or genotypes.
The usual purpose is to detect persons who themselves are at risk or whose offspring are at risk for a genetic disease or
a genetically determined susceptibility to an environmental agent. Genetic testing is performed to determine the genotype
of an individual suspected of having a mutation because of suggestive clinical features or a genetic relationship to a person
known to have the genetic abnormality in question.
